Thanks 'pdivizzle' i had forgot about photobucket
PETE

i added a photo of what happened to the first prototype

looks like a good thought, but when i was running the stock exhaust i just removed the entire thing all together and left just the spark arrestor in

i got one of the GYTR tip when i first bought my bike ( as shown in the photo)
ya i tried the exhaust with no tip, alittle loud for me, and i dont like wearing ear plugs
my prototype has to be better then the GYTR tip

it does look good though dont get me wrong.  im sure people looking to keep the stock pipe but want a little more performance would be all over it.  it might be a good idea to try and make one for the new WR450f since its the hot item at the moment. good luck!

this is this part listing from GYTR

Quiet GYTR® Performance WR Muffler Insert

Designed to be used with the stock exhaust system to offer a power increase while
